What type of battery does the Mistra car key use?
2 Answers
During daily use, if the battery runs out of power, remote control failure may occur. Once the battery is depleted, it is recommended that car owners replace it as soon as possible to avoid inconvenience. To replace the Mistra car key battery, follow these steps: 1. Remove the mechanical key. 2. Use a screwdriver to pry open the key, or partially insert the mechanical key into its slot and pry upwards. 3. Use the screwdriver to remove the old battery and install a new one. 4. Insert the new battery with the positive side facing up. 5. Reassemble the key in reverse order. 6. Test the lock and unlock functions to confirm proper operation.
Over the years of driving my own car, I've used the Hyundai Mistra key fob quite a few times. It typically uses CR2032 coin cell batteries - those small round button-type ones that are easily available in supermarkets or online. I remember panicking the first time it stopped working, thinking the key was broken, but it turned out to be just a dead battery that took mere minutes to replace. I recommend checking it every year or two; don't wait until it's completely dead. When replacing, first pry open the side of the key fob using a small screwdriver, being careful not to damage the circuit board. When installing the new battery, pay attention to polarity - positive side facing outward - then snap the case back together and the lights should work. Don't forget to check your spare key too, or you might face serious trouble if the main key fails. For convenience, opt for brand-name batteries like Panasonic or Sony - they last longer and prevent sudden failures.
